Murata Type 2FR is the world's smallest tri-radio IoT module with Wi-Fi 6, Bluetooth 5.4, and Thread connectivity

Murata has recently launched the world’s smallest tri-radio IoT modules, the Type 2FR/2FP series, as well as the Type 2KL/2LL series for hosted solutions. These compact modules feature tri-radio communication, including Wi-Fi 6, Bluetooth 5.4, and Thread, with Matter provisioning for interoperability. The 2FR/2FP series is considered the world’s smallest module (12.0 x 11.0 x 1.5mm) of this type with a built-in MCU, making it ideal for low-cost and highly integrated solutions. It prioritizes security with the latest cybersecurity standards and compatibility with the Matter ecosystem.

On the other hand, the 2KL/2LL series is designed to work with high-performance processors running Linux or RTOS. These modules provide reliable tri-radio communication with advanced capabilities. Both series are designed for applications, including smart homes, buildings, industrial automation, healthcare, and more, with features like low-power operation, extended battery life, and reduced component count.

Though Murata mentions the Type 2FR/2FP and Type 2KL/2LL modules in the same sentence, there is a major difference between the two: the Type 2FR has Thread (802.15.4) support whereas the Type 2FP module doesn’t support it. Similarly, the 2KL supports Thread (802.15.4), but not the Type 2LL. Other than that most of the other features stay the same.

We have previously written about other tri-radio IoT modules with WiFi, BLE, and 802.15.4 radios such as the u-blox MAYA-W4 and MAYA-W2 IoT modules, STMicro ST67W611M1, various ESP32-C6 modules, and several others. So the Murata Type 2FR joins a somewhat crowded market, but the main highlight is the claim that it is the world’s smallest tri-radio IoT SoCs with Thread, making it especially suitable for wearables and other space-constrained applications.

Both the 2KL/2LL and 2FR/2FP modules feature Wi-Fi 6, Bluetooth 5.4, and optional Thread connectivity. However, the 2KL/2LL (with the IW610F or IW610G chipset) is a much smaller (7.7 x 8.8 x 1.3 mm), simpler module designed for size-constrained applications where an external processor handles the main logic. The 2FR/2FP (with the RW610 chipset) integrates an Arm Cortex-M33 processor, enabling it to operate as a standalone solution with advanced security features and support for the Matter Smart Home protocol.

In terms of software, the Type 2KL/2LL module is offered with drivers for Linux, FreeRTOS, and Android platforms and interfaces with the host through SDIO v3.0 DDR50 for Wi-Fi and UART/PCM for Bluetooth. The Murata Type 2FR/2FP integrates an Arm Cortex-M33 real-time core supported by MCUXpresso and FreeRTOS platforms.

The evaluation kits for the Type 2FR SoC will be available in Q1 2025, and the product page implies an MOQ (minimum order quantity) of 2000 pieces for the SoCs. Murata did not mention any pricing information for the products. More technical information about the tri-band IoT modules and development board can be found in the documentation section of the product page, and the press release may have a few extra details too.
